Macro Photography Lens Stacking

As I’ve mentioned on my macros page, I’m not a macro photography purist.
I don’t focus on achieving a 1:1 life-size ratio when photographing a subject.
I do prefer using dedicated macro lenses (at least close focus) or macro techniques while doing close focus work as I find there is less distortion than with wide angle lenses.
I also enjoy trying anything that will spur my creativity.

This last winter, I was reading a website on extreme macro photography lens stacking and came across an article about using the Pentax M200/4 as a barrel lens for micro-photograpy work.
Extreme-Macro is a fantastic site for studying anything to do with close focus work. There is a wealth of information ranging from techniques to lenses, lighting or magnification calculations.
The page I stumbled upon mentioned the Pentax M200/4 as a wonderful lens to couple with a microscope objective for extreme work.

As I have an old M200 that doesn’t get used in this digital age, I decided to pull it out and see what I might be able to do with what I already had on hand or at least low cost investment.
A 52mm-52mm coupling ring, a 52mm-40.5mm step-down ring (which I did have to buy) and my old Rodagon 105/5.6 enlarging lens reverse mounted.
I must admit here that I am often lazy about using a tripod unless doing night shots and still prefer using an optical viewfinder over the rear lcd so achieving and maintaining focus with any depth of field would be a challenge.
I was surprised at how easy this combination was to hand hold and still achieve nice photos with a magnification of approx. 1.9:1.
Also, it was a fantastic pleasure to view something larger than life and try to see it in an artistic style.

Next I tried a reverse mount combination of the M200 with a Sigma 24/2.8 for a magnification ratio of approx. 8.3:1.
The added weight of the Sigma made it much harder to handhold but still produced nice results, though even at f16 the depth of field is very shallow.
This will take a lot more practice to get the my creative sight going.

I have been enjoying this new artistic view of the world so much that I just purchased an old EL-Nikkor 50/2.8 enlarging lens to use in the field (don’t want to take my Rodenstock out into the elements)
and am now on the hunt for an infinity focus objective plus adapter.

Lensbaby Plastic Optic Revisited

Very busy this month but I was able to revisit the Lensbaby Plastic Optic and play with a bit of Macro Photography in the yard.

These were taken using a de-glassed Takumar-A TC for an extension tube, approximately 27mm in length, giving around 1:2 magnification.

Very pleased with he results and really like the soft focus effect the lensbaby plastic optic offers.

IR Lens Hotspot Database

kolarivision.com has an excellent ir lens hotspot database already compiled; however, I noticed most of my older film lenses weren’t included so decided to create a database (bottom of page) testing these lenses on the Pentax K-01.

Pentax A50 f2.8 macro & K-1

Recently pulled out the old Pentax A50 f2.8 macro for a few shots of autumn leaves in the back yard.

This lens performs wonderfully on the new Pentax K-1. Though not a “true macro” with a reproduction of 1:2, I find the scale adequate and the IQ superb; plus it is such a joy to use.

I can see why vintage Pentax glass was noted for it’s quality, the colors are brilliant and the IQ is sharp for the area of focus. Bokeh is pleasantly pleasing also. This doesn’t seem to change on the new digital sensors either.

In fact, I find their performance is equal to or better than the newer digitally enhanced lenses.

 

National Automobile Museum – Reno

Every time I visit, I feel one of the most overlooked attractions, in Reno Nevada is the National Automobile Museum.

This place is amazing. It contains vintage automobiles in pristine and restored condition from the Harrah’s collection.

Era’s start with the early horseless carriages and vehicles built for commercial and race uses to the mid 1960’s. The history behind many of these vehicle is fascinating in itself but the architecture and art in their designs is beautiful.

Highly recommend this place for a visit. Entrance is in and out for the day and seldom more than a half dozen visitors at a time. Allows plenty of time to read, view and photograph this impressive collection.

Not much to write about this month, Just enjoying the Pentax K-1

Spending time this month reading about lenses and the Pentax K-1.

I find Pentax Forums a very nice resource for all sorts of material, lenses, cameras, flash, techniques – and not necessarily related to solely Pentax.
Easy to research articles and always someone willing to give a helpful reply.
Shots taken this month with the Pentax K-1 and various lenses or optics.

Pentax K1 testing Old Glass

Received the new Pentax K1 and decided to run a few test with the older vintage lenses I still have.

Nothing special with the images and minimal post processing, just to show the clarity. Have been pleasantly surprised with the results. I’ll list the lens below each shot posted for reference.

Kiron 28-105 2.8 (respectively), some vignetting at 28 and a little purple fringing. Still very sharp for its age. Shot at f8.

Tokina 70-210 4.5-5.6 (respectively), Slight purple fringing at 210, sharper than my current Sigma 70-200 2.8 APO DG. Shot at f8

Tamron SP90 Macro 1:1, very sharp. Shot at f8

yale lockset macro

Tokina 70-210 4.5-5.6 @210 with +10 Diopter, shot at f8. Some purple fringing with no hood but pleasantly surprised.

Why I appreciate a wide angle macro lens for regular close up photography.

Over the years I’ve found I enjoy close up photography more than any other type.

While not being true macro of 1:1 or 1:2 life size, I really like the feel and intimate perspective of being close to my subject.
With the advent of APS sized sensors in the Pentax line (which I shoot and am a proud Pentaxian), I find the crop factor to bring more of a telephoto angle of view than I really like.
I have eliminated most of my film era telephotos and focused on gaining lenses that will bring the wide angle perspective back to my view finder.
